(ci. 22o-4a) This invention relates to a box or container tiltingaction when opening the tin proceeds composed of sheet metal andfurnished with a without obstruction. The acute angle formed tiltinglid, and for the sake of brevity will be rebetween the upper edge of theridge and the tin ferred to in the following as a tin, this beingpossesses at the part of the tin where the ridge 5 the usual designationapplied to boxes or conis disposed downwards, and more particularly attainers of this character. the lowest point, the additional advantagethat At a certain distance from the upper edge the the lid is unable toslip when opening the tin, as tin possesses a ridge or ledge, a portionof which readily occurs in the known embodiments with is disposedangular-1y, that is to say-the ridge consequent injury to the fingers.It is 'also of l or ledge is not situated in a horizontal planeparticular advantage to make the wall of the l0 about the edge of thetin as usually applies in tin oblique or spherical in form immediatelyconnection with tins in which the lid simply ts above the inclinedportion of the ledge or ridge. over the edge, but ls disposed inclinedlydown- It is also desirable to draw, in the extreme wards over a part ofthe periphery, so that in upper edge of the tin in inclined or sphericall l this manner an angle or bend is formed.

ridge branohing off from the wall of the tin is that there Ais producedan angular` bend 1. B y

In this manner theedge of the tion of thel arrow l? at the point Aof location of lid issupported vertically to the ridge', and the the downwardly sloped ridgeportion 6, the lid' 55 is caused to tilt about the bendgor fulcra, I andassume the position shown in Fig. 2, the tin being opened.

According now to the invention, the upper edge t of the ridge 5,preferably at the point of the bend l, is situated substantially atright angles to the wall 8. of the tin. In this manner there is formedthe angle a, and the edge of the lid,

as shown in Fig. 3, is supported vertically against the portion 4. Whenpressure is applied to I,the lid-with reference to Fig. l-in thedirection of the arrow P, the lid is tilted about the fulcra 1 and thetin opened.

The ridge or ledge may 4also be constructed in the manner illustrated inFig. 4, in .which the ridge 5a is compressed. The primary feature alsoin this form of embodiment consists in the fact that a pressure exertedon the upper edge of the ridge in the direction of the arrow P1 actssubstantially vertically to this edge.

An additional form of embodiment is illustrated inFig. 5. In this casethe upper edge 4a of the ridge 5b assumes an acute angle b to the wall 8of the tin.

The essence of the invention will be particularly apparent from Fig. 6,which shows the known form of tin with ordinary ridge or ledge 5c. intothe wall 8 of the tin in'inclined or curved fashion.

When the lid 2 in Fig. 6 is pressed downwards inthe direction of thearrow P as in Fig.=1, there is no tilting of the lid about the bend l,andthe lid will merely move downwards along the curved or inclined face5d -of the ridge 5c, i. e., the edge 3 of the lid will be expanded atthis point, as the same is composed of thin sheet metal, and there willbe no support for tl'e tilting action of the lid as in the forms ofembodiment described in the above, so that a proper tilting movement isimpossible.

Fig. 7 shows that the upper edge of the wall of the tin is drawn in orrestricted in oblique or lspherical fashion above the downwardlydisposed The parts 5d and 5e of theridge pass over ridge portion 6 as at8a. Between this portion 'and the extreme edge of the wall, which isalso confined in inclined or spherical fashion, the wall has the normalcylindrical form, resulting in the advantage already described.

It is of course obvious that numerous modiiications are quite possiblewithin the meaning of the above description and the annexed claimwithout departing from the spirit of the invention.

What I claim as new Letters Patent is:

In a sheet metal container of the character described, a cylindricalcontainer body having a bottom and an upstanding peripheral wall, saidwall having a bead extending outwardly therefrom and spaced below thetop of the wall, said bead extending parallel to the top of the wall fora distance greater than one-half the circumference of the body and thenextending downwardly for the remainder of the circumference of the body,the junctions of the parallel and downwardly extending portions of thebeads forming fulcra, the wall above the downwardly extending portion ofthe bead being curved vertically substantially concentric to a linepassing through said fulcra and the opposite portion of the wall beingvertically curved inward from the bead upwardly, the bead at the fulcra,having its upper surface disposed at right angles to the wall andforming a sharp angle therewith, and a lid having a depending wallportion fitted on the body to have aV portion of its lower edge rest onthe rst mentioned portion of the bead, the wall portion -of the capbeing perpendicularly disposed with reference to the upper surface ofthe bead at the fulcra, whereby the lower edge of the lid is spacednormally from the downwardly inclined portion of the bead and wherebydownward pressure on the lid at a point above the downwardly inclinedportion will tilt the lid on said fulcra and desire to secure byAWithout spreading the portions of the wall resting on the fulcralaterally.
